This paper reports the results of a study of multiscale shape description, smoothing and representation. Multiscale nonlinear smoothing filters are first developed by using morphological openings and closings. These filters smooth signals while preserving their edges, and use a definition of scale that agrees with the spatial size of image objects. Matheron used openings and closings to obtain ...

In this paper, we provide a graph-based representation of the homology (information related to the different “holes” the object has) of a binary digital volume. We analyze the digital volume AT-model representation [8] from this point of view and the cellular version of the AT-model [5] is precisely described here as three forests (connectivity forests), from which, for instance, we can straigh...

This paper presents a unique application of computer vision methods designed to detect germination of lettuce seeds under controlled environment. Two steps involved in this application are image acquisition and image analysis which uses image skeletonization and other image processing algorithms. Seed images are converted to binary images followed by extraction of seed skeletons, which are used...

The main issue of this paper is to introduce some conditions for templatebased sequential thinning that are capable of producing the same skeleton for a given binary image, independent of the visiting order of object points. As an example, we introduce two order-independent thinning algorithms for 2D binary images that satisfy these conditions.

His research interest includes medical image registration, fusion and 3D parallel thinning algorithms. Attila Kuba is the head of the Department of Applied Informatics, JJ ozsef Attila University , Szeged. His research interests are image processing, its applications in medicine, image reconstruction and discrete tomography. Thinning is a frequently used method for extracting skeletons in discr...

osteological features are important to study the taxonomy and phylogenetic relationship of fishes. since there is no information is available about osteological features of squalius orientalis , therefore this study was aimed to provide a detailed description of the osteological features of this species from the urmia lake basin of iran and comparing it with population of s. orientalis from the...

nitrogen containing bisphosphonate (n-bp) therapy is used extensively to treat osteoporosis and osteolytic bone lesions. recently, a special form of osteonecrosis limited to the maxillofacial skeleton has been discovered especially within those patients who are receiving either long-term n-bp therapy alone and/or associated with invasive dental procedure. bisphosphonates accumulate almost exclu...

Machine learning tasks such as image classification need to select the features that can describe well. The has individual and common features, they are interdependent. If only of emphasized, neural network is prone overfitting. images networks will not be able adapt diversified environments. In order better integrate based on skeleton edge extraction, this paper designed a mixed feature extrac...
